2 OFFICE OF INSPECTOR GENERAL The mission of the Office of Inspector General (OIG), as mandated by Public Law , is to protect the integrity of the Department of Health and Human Services programs as well as the health and welfare of beneficiaries served by them. This statutory mission is carried out through a nationwide program of audits, investigations, inspections, sanctions, and fraud alerts. The Inspector General informs the Secretary of program and management problems and recommends legislative, regulatory, and operational approaches to correct them. Office of Evaluation and Inspections The Office of Evaluation and Inspections (OEI) is one of several components of the Office of Inspector General. It conducts short-term management and program evaluations (called inspections) that focus on issues of concern to the Department, the Congress, and the public. The inspection reports provide findings and recommendations on the efficiency, vulnerability, and effectiveness of departmental programs. OEI's San Francisco Regional Office prepared this report under the direction of Paul A. Gottlober, Regional Inspector General. Principal OEI staff included: REGION IX Deborah Harvey, Project Leader Christopher Tarbell, Lead Analyst Robert Gibbons, Program Analyst Camille Harper, Program Analyst Scott Hutchison, Program Analyst Steven Zerebecki, Program Analyst HEADQUARTERS Susan Burbach, Program Specialist Linda Moscoe, Technical Support Staff Brian Ritchie, Technical Support Staff Bambi Straw, Program Specialist Stuart Wright, Director, Medicare and Medicaid Branch To obtain copies of this report, please call the San Francico Regional Office at (415) Reports are also available on the World Wide Web at our home page address:

3 EXECUTIVE SUMMARY PURPOSE This inspection analyzed the medical necessity, cost, and medical record documentation of physical, occupational, and speech therapy provided to nursing home patients in calendar year 1999 and billed to Medicare Part B by nursing homes, rehabilitation agencies, or hospital outpatient departments. BACKGROUND Medicare coverage guidelines state that all therapy must be reasonable, necessary, specific, and effective treatment for the patient s condition. Therapy must be ordered by a physician or other qualified health care professional, require the skills of a qualified therapist, and be dictated by a written treatment plan. The plan must include specific and measurable goals and a reasonable estimate of when the patient will attain the goals. In 1997, Congress changed nursing home reimbursement for therapy by setting two annual caps. Occupational therapy was limited to $1500 annually, while physical and speech therapy shared the same $1500 annual cap. In November 1999, the caps were suspended for 2 years effective January 1, The moratorium on the therapy caps has subsequently been extended through calendar year The law that suspended the caps also requires the Centers for Medicare and Medicaid Services (formerly known as the Health Care Financing Administration) to (1) recommend a process to assure the appropriate utilization of Medicare outpatient therapy and (2) establish an alternative payment policy based on diagnostic categories, functional status, and prior use of therapy. To meet the requirements of the law, Agency staff requested our assistance. Our national random sample consisted of 320 Medicare patients. We conducted on-site medical and financial reviews at 132 nursing homes, rehabilitation agencies, and hospital outpatient departments. Several teams of physical and occupational therapists and speech-language pathologists reviewed the medical records for 318 of the sampled patients. FINDINGS The $1500 therapy caps did not prevent Medicare nursing home beneficiaries from receiving necessary and appropriate therapy Less than 2 percent of Medicare beneficiaries reached either of the $1500 therapy caps. While the caps were in place, beneficiaries required no additional therapy in Nursing Home Therapy Under the $1500 Caps 1 OEI

4 approximately 82 percent of therapy episodes. Furthermore, although physical and speech therapy shared a cap, most beneficiaries received the physical and speech therapy they needed. Despite the therapy caps, 14 percent of all therapy was not medically necessary Although most therapy was deemed medically necessary, 14 percent was not. Medicare allowed more than $28 million during the first 6 month of 1999 for these medically unnecessary services. Therapy was medically unnecessary because (1) patients were not appropriate candidates; (2) treatment goals were met, but therapy continued; (3) therapy goals were not achieved, and a reevaluation was not conducted; or (4) skilled therapy was provided instead of routine maintenance. Approximately 10 percent of the therapy units were not supported by adequate documentation Medicare paid nursing homes approximately $12 million for undocumented units and an additional $8 million for inadequately documented units during the first 6 months of Physician s orders were not included in some medical records Medicare guidelines state that therapy must be ordered in advance by a physician or other health care professional and documented in writing in the medical record. We were unable to locate physician s orders for approximately 5.6 percent of the total therapy units billed to Medicare in the first 6 months of Medicare paid nursing homes approximately $10.6 million for these units. Since the focus of our study was to determine the medical necessity, quality of care, and utilization of therapy, some of these units may have been included in the calculations for medically unnecessary, undocumented, and inadequately documented units. Medicare allowed in error approximately $48.5 million for Part B therapy for nursing home patients during the first 6 months of This includes $28.7 million for medically unnecessary therapy, $12.2 million for undocumented therapy units, and $7.6 million for inadequately documented therapy units. These three categories represent an overall error rate of 24.7 percent of the total allowed amount of approximately $196.5 million for Part B therapy during the first 6 months of Our sampling methodology does not allow us to make statistically valid projections for the entire year. However, if we assume that the second half of 1999 was the same as the first 6 months of 1999, we estimate that the amount Medicare allowed for unnecessary, undocumented, and inadequately documented therapy was $97 million.

5 RECOMMENDATIONS The Centers for Medicare and Medicaid Services (CMS) should: < encourage fiscal intermediaries to continue educating nursing homes on Part B billing and Medicare requirements for record documentation and retention, with an emphasis on the proper documentation of physician s orders in patients records; < instruct fiscal intermediaries to conduct focused medical review in order to identify and collect Part B therapy overpayments; < continue working collaboratively with the national therapy associations to assure that they provide accurate and comprehensive information to their members on proper documentation of therapy in medical records; and < consider options when developing a new reimbursement system for Part B therapy, such as (1) reimbursement based on an episode of therapy and (2) prior authorization for therapy that exceeds a separate monetary cap for each type of therapy. AGENCY RESPONSE We received comments on the draft report from CMS. The Agency concurred with our recommendations. They will continue to educate nursing homes on Medicare Part B billing and medical record documentation and continue to recommend that fiscal intermediaries conduct focused medical review whenever their analysis suggests egregious overutilization of services. The CMS will consider options when developing a new reimbursement system for Medicare Part B therapy. Finally, CMS will continue its ongoing collaboration with the national therapy associations to provide information on proper documentation of therapy in medical records.

7 INTRODUCTION PURPOSE This inspection analyzed the medical necessity, cost, and medical record documentation of physical, occupational, and speech 1 therapy provided to nursing home patients in calendar year 1999 and billed to Medicare Part B by nursing homes, rehabilitation agencies, or hospital outpatient departments. BACKGROUND Medicare Coverage for Skilled Nursing Facilities All skilled nursing facilities (SNFs) must meet the requirements of Section 1819 of the Medicare law. The SNFs must, for example, (1) provide 24-hour skilled nursing service under policies developed by physicians, registered nurses, or other professionals; (2) develop health plans for each patient, under the supervision of a physician; (3) maintain clinical records on all patients; and (4) meet a number of conditions to assure patients health and safety. All SNFs are required to assess each patient s status and needs shortly after admission, including the need for physical, occupational, and speech therapy. The Nursing Home Reform Act (P.L ), which Congress passed as part of the Omnibus Budget Reconciliation Act of 1987, requires that SNFs assess all patients needs within 14 days of admission and reassess long-term patients annually. A physician must see the patient at least every 30 days. 2 If a patient needs therapy over a period of time under the same treatment plan, the physician must recertify the continuing need for therapy every 30 days and estimate how long the patient will need therapy. 3 Fiscal intermediaries, the insurance companies that process and adjudicate Medicare claims for inpatient hospitals and SNFs, often develop local medical review policies to supplement Medicare guidelines for medical necessity and utilization. 1 Throughout this report, we will refer to speech-language pathology as speech therapy. 2 Health Care Financing Administration, Skilled Nursing Facility Manual, Sections 214, 230, 230.3(C), and Ibid., Section 271.1B.

8 Descriptions of Physical, Occupational, and Speech Therapy Physical therapy includes, but is not limited to, (1) examining patients with impairments, functional limitations, disabilities, or other health-related conditions to determine a diagnosis, prognosis, and intervention; (2) alleviating impairments and functional limitations by designing, implementing, and modifying therapeutic interventions; and (3) preventing injury, impairment, functional limitation, and disability, including the promotion and maintenance of fitness, health, and quality of life. 4 Common treatments include therapeutic exercise, prescription and customization of prosthetic devices and equipment, and wound management. Occupational therapy is the use of purposeful activity or interventions designed to achieve constructive outcomes which promote health and/or prevent injury or disability, and which develop, improve, maintain, or restore the highest possible level of independence of any individual who has an injury, illness, cognitive impairment, psycho social dysfunction, mental illness, developmental or learning disability, physical disability, or other disorder or condition. 5 Occupational therapy primarily focuses on compensatory techniques to improve a patient s ability to complete independently the activities of daily living. An example includes teaching a stroke patient new techniques to eat and dress himself as independently as possible. 6 Speech therapy includes (1) services for patients with speech, hearing, and language disorders which result in communication disabilities and (2) the diagnosis and treatment of swallowing disorders, regardless of the presence of a communications disability. Communication disabilities most frequently affect patients with cerebrovascular disease (e.g., stroke), Parkinson disease, multiple sclerosis, and laryngeal carcinoma. Patient conditions may include (1) hearing sounds faintly, in a distorted way, or not at all; (2) substituting simple sounds; or (3) lacking the ability to use speech and language. 7 Therapy may include, but is not limited to, diagnostic, screening, preventive, or corrective services provided by or under the direction of a speech-language pathologist or 4 American Physical Therapy Association, Model Definition of Physical Therapy for State Practice Acts, Board of Directors Policies, Positions and Guidelines, March The American Occupational Therapy Association, Inc.

Medicare Coverage and Cost of Physical, Occupational, and Speech Therapy Coverage guidelines for Part B therapy. Medicare guidelines state that all therapy must be reasonable, necessary, specific, and effective treatment for the patient s condition. The Centers for Medicare and Medicaid Services (formerly known as the Health Care Financing Administration or HCFA), the federal agency that administers the Medicare program, requires that therapy (1) is ordered by a physician or other qualified health care professional, (2) requires the skills of a qualified therapist rather than nonskilled SNF staff, (3) is provided either by or under the direct supervision of a certified therapist (as defined in State law), and (4) is dictated by a written treatment plan. Nursing home charges for Part B therapy. Part B therapy increased from 1999 to In the first 6 months of 1999, nursing homes charged the Medicare program $271 million for Part B therapy for 328,000 beneficiaries. In the first 6 months of 2000, the charges increased to $316 million for 348,000 beneficiaries.

10 Medicare Guidelines for Documentation and Retention of Medical Records Medical records should include documentation that describes all treatments and the patient s progress throughout the episode of therapy. Documentation should include, but is not limited to: < written or telephone physician s order for the therapy (telephone orders should be documented in the medical record by a nurse and then confirmed in writing by the physician or other health care professional as soon as possible); < initial examination and evaluation by the therapist describing the patient s history, admitting and treatment diagnoses, initial functions, diagnosis, short and long-term treatment goals, and the treatment plan; < information for each therapy session, also called treatment logs or daily notes, describing the types and length of the types of therapy that the patient received and who provided the therapy (therapist, assistant, or aide); < progress notes explaining the patient s progress or lack of progress on the treatment plan; < reexaminations and re-evaluations (at least monthly for the same episode of therapy) confirming the continued need for therapy; and < discharge summary which is required at the end of the episode of therapy. 11 The Centers for Medicare and Medicaid Services (CMS) requires that nursing homes retain medical records for 5 years after the patient is discharged. 12 If the nursing home contracted with independent providers (such as a therapy provider) to render services, Medicare guidelines require that nursing homes retain all records for 3 years after final payment under the contract. 13 The Therapy Caps Section 4541(c) of the Balanced Budget Act of 1997 changed SNF reimbursement for physical, occupational, and speech therapy by setting two annual caps for Medicare Part B patients. Effective January 1, 1999, occupational therapy was limited to $1500 annually, while physical and speech therapy shared the same $1500 annual cap American Physical Therapy Association, Guide to Physical Therapist Practice, appendix 7, 12 Health Care Financing Administration, Skilled Nursing Facility Manual, Chapter V Billing Procedures, Section Peer Review Organization Manual, Part 13--Management, Section Nursing Home Therapy Under the $1500 Caps 8 OEI

11 Section 221 of the Medicare, Medicaid, and SCHIP 14 Balanced Budget Refinement Act of 1999, passed in November 1999, suspended the cap for 2 years effective January 1, Section 221(c)(2) of the Law requires CMS to (1) recommend a mechanism to assure the appropriate utilization of Medicare outpatient therapy and (2) establish an alternative payment policy based on diagnostic categories, functional status, and prior use of therapy. 15 Focused Medical Review The 1999 law also mandated that the Secretary conduct focused medical reviews of Part B therapy claims, with an emphasis on SNF claims in calendar years 2000 and In October 2000, CMS launched a Program Safeguard Contract for therapy to (1) analyze current national and local medical review policies; (2) conduct extensive literature review, analysis, and abstraction; (3) interview fiscal intermediaries and therapy providers; and (4) develop medical review protocol for the fiscal intermediaries. Section 421 of the Medicare, Medicaid, and SCHIP Benefits Improvement and Protection Act of 2000, passed in November 2000, extended the moratorium on the therapy caps for another year, through calendar year The law also extended the requirement for focused review of SNF therapy claims until year Previous Office of Inspector General Work The Office of Inspector General released two reports in August 1999 concerning physical and occupational therapy rendered to Medicare patients in nursing homes. We found that most Medicare patients received appropriate therapy for their initial medical conditions and benefitted from therapy. However, almost 13 percent of physical and occupational therapy was billed improperly because it was not medically necessary and/or the therapy was provided by staff who did not have the appropriate skill. During the 12-month period before implementing the SNF prospective payment system, Medicare paid SNFs almost $1.3 billion for the unnecessary and improperly documented therapy. 16 In our report entitled Monitoring Part B Therapy for SNF Patients, we noted that there was a dramatic decrease in Part B therapy charges during The decrease may be explained by the requirement that, as of January 1999, reimbursement changed from cost-based to the Medicare Part B fee schedule. However, preliminary reports indicate that a rebound in SNF Part B therapy charges may occur because of the moratorium on 14 State Children s Health Insurance Program. 15 The Social Security Act, Section 1833(g) as amended. 16 Office of Inspector General, Physical and Occupational Therapy in Nursing Homes: Quality of Care and Medical Necessity for Medicare Patients (OEI ), and Physical and Occupational Therapy in Nursing Homes: Cost of Improper Billings to Medicare (OEI ), August Nursing Home Therapy Under the $1500 Caps 9 OEI

12 the caps and the lack of adequate contractor oversight of billing practices and medical necessity. We recommended that CMS ensure that adequate medical reviews of Part B therapy in SNFs are conducted. We also recommended that CMS continue working with therapy providers to improve their understanding of Medicare billing procedures and the medical necessity guidelines for Part B therapy. METHODOLOGY Selection of Sampled SNF Part B Therapy Patients From the Medicare Common Working File, we extracted all Part B physical, occupational, and speech therapy claims for services provided to SNF patients. 17 These claims were submitted to intermediaries by SNFs, rehabilitation agencies, and hospital outpatient departments for therapy initiated between January 1 and June 30, We limited the extract to the continental United States. We used a multi-stage stratified clustered sample. We clustered the Medicare Part B therapy patients into groups of similar size in the same geographical area. We then stratified the clusters into four quadrants of the United States. We randomly selected 4 clusters per quadrant for a total of 16 clusters. We used the 75 th percentile of each cluster s estimated therapy reimbursement to group patients into two groups. Group 1 contained the 25 percent of patients with the highest therapy reimbursement. Group 2 contained the remaining 75 percent. For each cluster, we stratified patients within both groups and then selected 20 patients as follows: Stratum I--patients with the highest reimbursement in Group 1 8 Stratum II--random selection of additional patients from Group 1 8 Stratum III--random selection of patients from Group 2 4 Our sample for all clusters totaled 320 patients. On-Site Medical and Financial Review Total patients per cluster 20 Several teams of certified and/or licensed physical and occupational therapists and speech-language pathologists conducted on-site review of the medical records for the national random sample. Reviewers used medical review instruments to assess the medical necessity, underutilization, overutilization, and quality of care provided in 17 We identified beneficiaries as SNF patients if (1) the SNF submitted the claims, or (2) the beneficiaries were identified as SNF residents in CMS minimum dataset (MDS).

13 calendar year The reviewers also determined if the record documentation and the information on the Medicare claims accurately reflected the types of therapy and the appropriate length of treatment that the patients received. While on-site, in addition to the medical review, we: < reviewed therapy ledgers to determine how SNFs track each patient s charges that were billed to Part B of Medicare; < gathered data to identify payment sources for patients in addition to Medicare reimbursement; < interviewed SNF administrators and key therapy staff about how they tracked the cap and their interactions with their fiscal intermediaries; and < observed physical, occupational, and speech therapy conducted with patients. We conducted interviews at 132 facilities--97 SNFs, 28 hospital outpatient departments, and 7 rehabilitation agencies located in 18 States. We obtained the medical records for 318 of the 320 sampled patients. We were unable to review two patient records because the facility had closed before our review, and the corporate owner could not retrieve the records from storage. Claims Analysis We analyzed the Part B physical, occupational, and speech therapy claims submitted for the sampled patients. For each patient, we extracted only claims that were submitted for therapy initiated between January 1 and June 30, We analyzed the claims by individual therapy units and clusters of therapy units. An individual unit of physical, occupational, or speech therapy constitutes one 15-minute session of therapy. Clusters of units were grouped into an episode of care. An episode of care consists of a series of continuous therapy units tied to a specific diagnosis, treatment plan, and set of patient goals. An episode of care may last a few days or a few months. The Balanced Budget Act of 1997 mandated that nursing homes use the CMS Common Procedural Coding System to describe each type of therapy that patients receive. Medicare Part B therapy claims must include both the code and the number of 15-minute sessions, or units, for each type of therapy. To illustrate, an occupational therapist works with a patient on the activities of daily living, such as bathing and dressing, for 45 minutes. The Medicare claim would include the appropriate code with three units for the length of the treatment. Cost projections were based on an analysis of the extracted Part B physical, occupational, and speech therapy claims. Information found on each claim was used to calculate the estimated amount that Medicare allowed for each therapy claim. Cost projections then Nursing Home Therapy Under the $1500 Caps 11 OEI

14 were calculated using the lower of the calculated Medicare allowed amount or the fiscal year 1999 Medicare fee schedule amount. This report is one of two reports on physical, occupational, and speech therapy for Medicare SNF patients. The other report, Physical, Occupational, and Speech Therapy for Medicare Nursing Home Patients: Medical Necessity and Quality of Care based on Treatment Diagnosis (OEI ), focuses on the medical necessity and quality of care for different therapy diagnoses. Our review was conducted in accordance with the Quality Standards for Inspections issued by the President s Council on Integrity and Efficiency. Nursing Home Therapy Under the $1500 Caps 12 OEI

15 FINDINGS The $1500 therapy caps did not prevent Medicare SNF beneficiaries from receiving necessary and appropriate therapy Less than 2 percent of Medicare beneficiaries reached either of the $1500 therapy caps Nationally, 0.5 percent of Medicare Part B patients who began therapy between January and June 1999 reached or exceeded the $1500 occupational therapy cap within 6 months, and only 1.7 percent of patients reached or exceeded the shared $1500 physical and speech therapy cap. The average Medicare allowance for patients who received occupational therapy was $516, and the average Medicare allowance for physical and speech therapy patients was $503. In approximately 82 percent of therapy episodes, beneficiaries required no additional therapy In most of the episodes of care, 18 patients needed no additional therapy by the time their treatment ended. To determine if additional therapy was needed, medical reviewers examined medical records, treatment logs, and physician orders for each episode of care. Reviewers discovered patients rarely needed additional therapy to reach their treatment goals or patients would not have benefitted from additional therapy. For example, one occupational therapy patient received treatment once a day for approximately 3 weeks. After reviewing his record, one medical reviewer suggested, This is a well documented case showing appropriate improvement in a reasonable time. There was good rationale for discharging... With regard to the remaining 18 percent, we found that in approximately 12 percent of the episodes patients actually needed additional therapy. For the rest, reviewers were unable to make a determination. Patients received therapy beyond the caps because SNFs ignored the caps or were unaware of them According to administrators, SNFs rarely discontinued therapy when patients reached the therapy caps. When they reached the $1500 cap, beneficiaries and their families were 18 An episode of care consisted of a series of continuous therapy units tied to a specific diagnosis, treatment plan, and patient goals. Nursing Home Therapy Under the $1500 Caps 13 OEI

16 presented with the option of switching to another type of insurance or paying for therapy costs out of their own pocket. Administrators indicated that, in some cases, they continued to provide therapy to patients and absorbed the extra costs themselves. A lack of education on Part B therapy also caused some SNFs to provide therapy to patients after they had reached or exceeded the $1500 caps. Staff in more than half of the facilities we interviewed reported not receiving training from fiscal intermediaries on Part B therapy. According to administrators, this often left them unclear on new billing requirements, including the therapy caps. Administrators in these facilities indicated that they were unaware of how to monitor the therapy caps, and, subsequently, costs were not tracked. Despite the therapy caps, 14 percent of all therapy was not medically necessary Although most therapy was medically necessary, some was not. Medical reviewers deemed that 88 percent of physical therapy was medically necessary, 86 percent of occupational therapy was medically necessary, and 67 percent of speech therapy was medically necessary. This included therapy that was undocumented or inadequately documented, since reviewers were instructed to deem therapy medically necessary when documentation was absent or inadequate. MOST THERAPY WAS MEDICALLY NECESSARY Therapy Medically Necessary Therapy Therapy Units Billed (approximate) All Therapy Therapy Type Physical Occupational Speech 85.7 percent 87.7 percent 86.3 percent 66.7 percent 9,000,000 6,000,000 2,000, ,000 Source: Office of Evaluations and Inspections, 2001 Most SNF patients were diagnosed properly, and a necessary treatment plan was developed for each diagnosis. Therapists usually updated treatment plans when a patient s progress or condition changed, and therapy usually was administered with the proper frequency and duration. Reviewers also found that most Medicare patients benefitted from these services, and medically necessary therapy helped them reach their treatment goals. Nursing Home Therapy Under the $1500 Caps 14 OEI

17 Medical reviewers also found that some Medicare SNF patients received medically unnecessary therapy. Reviewers identified several reasons why 14 percent of therapy was medically unnecessary including, but not limited to: < patients were not appropriate candidates based on their condition; < treatment goals were being met, but therapy continued; < therapy goals were not being achieved, and a reevaluation was not conducted; or < skilled therapy was provided instead of the routine maintenance that was more appropriate for the patients s condition. Medical reviewers found that the medical condition of some SNF patients did not indicate the need for skilled therapy. The diagnosis of some patients indicated that therapy would not have benefitted the patient, or the therapist should have postponed therapy until the patient s medical condition stabilized. For example, one occupational therapy patient with a questionable cognitive condition received unnecessary therapy three times a week for 3 weeks, without improvement. The patient s lack of motivation to participate in a previous therapy episode should have alerted the provider that this patient was not an appropriate candidate for therapy. 19 Some therapy episodes continued 1 to 2 weeks beyond what was medically necessary. Medical reviewers noted that therapy continued because, among other reasons, a patient s medical condition had plateaued or SNFs did not properly monitor patient progress. In one rural facility, four out of the five patients in our sample received physical therapy from 1 to 4 weeks longer than was medically necessary. Reviewers also questioned why therapists continued to provide care that was not supported by documentation. The SNFs continued to provide therapy, in some cases, to patients who were not meeting their treatment goals. Medical reviewers indicated that when a patient does not reach their treatment goals, therapy should be reevaluated and possibly discontinued. However, several facilities used a cookie-cutter treatment plan for all Medicare SNF patients. Therapy continued regardless of a patient s medical status. For example, one beneficiary received occupational therapy for 3 months without reaching her treatment goals. As the medical reviewer suggested,...this case did not meet the Medicare guidelines of significant practical improvement over a reasonable time period, and treatment should have been discontinued. Medical reviewers found that some patients did not need skilled speech therapy. Nursing home staff should have provided maintenance instead of skilled speech-language pathologists providing maintenance. For example, it was standard practice in many SNFs 19 The effects of medical condition, or diagnosis, on medical necessity and quality of care is discussed in our companion report, Physical, Occupational, and Speech Therapy for Medicare Part B Nursing Home Patients: An Analysis of Medical Necessity and Quality of Care based on Treatment Diagnosis, OEI , July Nursing Home Therapy Under the $1500 Caps 15 OEI

18 to bill an evaluation and several units of treatment for changing a patient s diet as skilled speech therapy. This therapy should have been delivered by the nursing home staff after the speech-language pathologist evaluated the patient and recommended the appropriate changes. Medicare allowed approximately $28 million for unnecessary therapy in the first 6 months of 1999 The Medicare program allowed almost $15 million for unnecessary physical therapy, $6.4 million for unnecessary occupational therapy, and $7.5 million for unnecessary speech therapy during the first 6 months of 1999, while the therapy caps were in effect. MEDICARE PAYS FOR UNNECESSARY THERAPY Reimbursement Type Allowed amount for unnecessary units Total allowed amount All Therapy (Millions) $28.7 $196.5 Therapy Type (Millions) Physical Occupational Speech $14.7 $6.4 $7.5 $121.4 $49.0 $26.0 Source: Office of Evaluations and Inspections, 2001 The mean Medicare allowance for physical, occupational, and speech patients was higher with medically unnecessary therapy than without medically unnecessary therapy. We discovered that the mean allowance for physical therapy patients was at least $57 higher than it should have been, at least $54 higher for occupational therapy patients, and more than $76 higher for speech therapy patients. These higher payments were all a result of Medicare paying for medically unnecessary services. Our sampling methodology does not allow us to make statistically valid projections for the entire year. Nevertheless, if we assume that the rate of medically unnecessary therapy for the second half of the year was the same as it was for the first 6 months, Medicare allowed approximately $56 million dollars for unnecessary therapy during Patients who reached or exceeded the caps received medically unnecessary therapy Eighty percent of the 2 percent of Medicare beneficiaries who reached either of the therapy caps received some unnecessary therapy. Medicare allowed between $1500 and $2800 for patients who reached the occupational therapy cap, with unnecessary therapy totaling anywhere from zero to $1500. Similarly, the amount allowed for Medicare SNF patients who reached or exceeded the shared physical and speech therapy cap was Nursing Home Therapy Under the $1500 Caps 16 OEI

19 between $1500 and $2700, with unnecessary therapy totaling anywhere from zero to $1900. Sixty-three percent of the 1.7 percent of patients who reached the shared therapy cap would not have done so if they had received medically necessary therapy only. Similarly, approximately 76 percent of the 0.5 percent of beneficiaries who reached or exceeded the occupational therapy cap would not have done so had they received medically necessary therapy only. For example, more than 50 percent of the units billed to Medicare for one patient who exceeded the occupational therapy cap were medically unnecessary. Although physical and speech therapy shared a cap, most beneficiaries received the physical and speech therapy they needed Less than 10 percent of SNF patients needed speech and/or physical therapy and did not receive them Medical reviewers confirmed that when most patients did not receive physical or speech therapy it was because therapy would not have benefitted their medical condition. For example, after confirming that one patient needed no speech therapy, a medical reviewer noted, Patient previously received speech therapy from October 1998 to January 1999, was discharged due to a lack of progress. Approximately 2 percent of beneficiaries reached the shared cap at any time during calendar year 1999 Very few patients were prevented from receiving physical or speech therapy because they reached the $1500 shared cap. An analysis of the complete 1999 claims history showed that no more than 2 percent would have reached the shared cap. Approximately 1 percent of sampled beneficiaries would have reached the shared cap if Medicare had paid for medically necessary therapy only. 20 As mentioned earlier, possible explanations for why patients reached the cap include lack of training by fiscal intermediaries on Part B therapy, unnecessary therapy, or disregard for the therapy caps by providers. 20 We excluded all unnecessary services received by each patient during Nursing Home Therapy Under the $1500 Caps 17 OEI

20 Approximately 10 percent of the therapy units were not supported by adequate documentation We used the decisions of medical reviewers to determine how we would quantify documentation errors within our sample. Some episodes of therapy lacked any supporting documentation. For these episodes, reviewers were unable to determine if therapy was medically necessary. We counted all the billed therapy units associated with these episodes as undocumented. In other instances, reviewers determined that the episode of therapy was medically necessary, although some individual units were undocumented or inadequately documented. We counted these units accordingly. Overall, Medicare paid almost $20 million for therapy units that were undocumented or not documented adequately in the first 6 months of 1999 Medicare paid approximately $12 million for undocumented therapy units during the first 6 months of 1999 Undocumented therapy Physical Type of Therapy Occupational Speech Total for All Undocumented Units Percent of units Medicare payment 8.0% $8.7 million 5.9% 3.3% 7.1% $ 2.8 million $730,000 $12.2 million Source: Office of Evaluation and Inspections, 2001 Although reviewers found some documentation in medical records to support almost 93 percent of therapy units, documentation was missing for approximately 7 percent of the units. The progress notes for some billed units did not describe all types of therapy provided in the session. For example, one patient s Medicare claim included 45 minutes of therapy each day for 21 consecutive days. The reviewer noted that the medical record contained documentation for 30 minutes of therapy each day rather than 45 minutes. In other instances, Medicare claims included units for some therapy that patients did not receive. For example, one claim included one unit for 15 minutes of gait training on 2 consecutive days. However, the therapist stated in the progress notes that the patient refused treatment on both days. Nursing Home Therapy Under the $1500 Caps 18 OEI

21 Medicare paid approximately $8 million for inadequately documented therapy units during the first 6 months of 1999 Inadequately Documented Therapy Type of Therapy Physical Occupational Speech Total for All Inadequately Documented Units Percent of units Medicare payment 3.4% 0.7% 6.8% 2.9% $4.3 million $333,000 $2.9 million $7.6 million Source: Office of Evaluation and Inspections, 2001 Because almost 3 percent of therapy units were not documented adequately, reviewers were unable to determine the full range of therapy that patients received. Progress notes, which are intended to document how patients were progressing for each type of therapy, were incomplete in some medical records. For example, one patient received three types of therapy in each session--exercises to build strength and endurance, neuromuscular reeducation, and direct therapeutic activity with the therapist. The same types of therapy continued for 12 days between January and March However, the medical reviewer found that the documentation was adequate for only two of the three types of treatment in each session, but was consistently inadequate for the third type. Physician s orders were not included in some medical records Medicare guidelines state that therapy must be ordered in advance by a physician or other health care professional and documented in writing in the medical record. We were unable to locate a telephone or written order for some of the therapy episodes in our sample. The lack of orders corresponds to approximately 5.6 percent of the total therapy units billed to Medicare in the first 6 months of However, medical reviewers still determined the medical necessity, quality of care, and utilization of therapy for these units. Several reasons for missing orders may include: < a separate log of all physician s orders was missing from a patient s medical record, < the medical record included a signed order for the first therapy episode but not for subsequent episodes, or < physicians did not countersign telephone orders as required by Medicare guidelines.

22 For example, one patient received physical therapy in two episodes. We found a physician s order for the first episode in February Therapy lasted 1 month. The patient began another episode of therapy in May and received therapy for 3 months. However, we did not locate a physician s order for the second episode of therapy. Medicare paid nursing homes approximately $10.6 million for these therapy units. Since the focus of our study was to determine the medical necessity, quality of care, and utilization of therapy, some of these units may have been included in the calculations for medically unnecessary, undocumented, and inadequately documented units. Some SNFs did not retain medical records according to Medicare guidelines Medicare guidelines require that SNFs retain medical records for 5 years after the patient is discharged. We reviewed medical records for therapy provided 12 to 20 months before our review. Some SNFs were unaware that records were missing until our review. In some cases, records were missing because (1) therapy notes were purged from the records for long-term patients, sent to storage, and subsequently misplaced or (2) the SNF changed therapy providers during 1999, and the previous provider removed the therapy records from the facility. By removing records, therapy providers may have violated their contracts. Several contracts that we reviewed contained language such as, All case records, case histories, personal and regular files concerning patients of the facility or facility patients consulted, interviewed, or treated and cared for by the provider shall belong to and remain the property of the facility. In fact, contracts between SNFs and independent therapy providers often stated that therapy records should be retained in patients records and available for a minimum of 4 years after the contract expired. Medicare allowed in error approximately $48.5 million for Part B therapy during the first 6 months of This includes $28.7 million for medically unnecessary therapy, $12.2 million for undocumented therapy units, and $7.6 million for inadequately documented therapy units. These three categories represent an overall error rate of 24.7 percent of the total allowed amount of approximately $196.5 million for Part B therapy during the first 6 months of Our sampling methodology does not allow us to make statistically valid projections for the entire year. However, if we assume that the second half of 1999 was the same as the first 6 months of 1999, we estimate that the amount Medicare allowed for unnecessary, undocumented, and inadequately documented therapy was $97 million.

23 RECOMMENDATIONS The CMS should: Encourage fiscal intermediaries to continue educating SNFs on Part B billing and medical record documentation More than half of all administrators told us that SNFs did not receive any training from the fiscal intermediary on billing for Part B therapy. Nursing home administrators and billing staff often remarked that they did not know how their facility billed therapy (charges or the fee schedule), and they were not aware that therapy reimbursement was based on the Part B fee schedule. Fiscal intermediaries should also educate SNFs and their staff on Medicare requirements for medical record documentation and retention, with an emphasis on the proper documentation of physician s orders in patient records. Instruct fiscal intermediaries to conduct focused medical review in order to identify and collect Part B therapy overpayments Using focused medical review we identified approximately $28 million in overpayments for medically unnecessary Part B therapy services in the first 6 months of Instructing fiscal intermediaries to conduct similar focused medical review could result in significant cost savings for the Medicare program. Consider options when developing a new reimbursement system for Part B therapy As mentioned in the background, Section 221 of the Medicare, Medicaid and SCHIP Balanced Budget Refinement Act of 1999 requires that CMS establish an alternative payment policy for SNFs. Based on our inspection, we suggest that CMS consider: < basing reimbursement on an episode of therapy rather than an annual cap, and/or < requiring prior authorization for therapy that exceeds a separate monetary cap for each type of therapy. Continue working collaboratively with the national therapy associations We believe that poor documentation is a result of a lack of awareness and understanding of Medicare guidelines and requirements on the part of SNFs and therapists. By working with the national associations, CMS can assure that they provide accurate and Nursing Home Therapy Under the $1500 Caps 21 OEI

24 comprehensive information to their members on proper documentation of therapy in medical records. AGENCY RESPONSE We received comments on the draft report from CMS. The Agency concurred with our recommendations. They will continue to educate nursing homes on Medicare Part B billing and medical record documentation and continue to recommend that fiscal intermediaries conduct focused medical review whenever their analysis suggests egregious overutilization of services. The CMS will consider options when developing a new reimbursement system for Medicare Part B therapy. Finally, CMS will continue its ongoing collaboration with the national therapy associations to provide information on proper documentation of therapy in medical records.
